I wasn't aware that there was a flag to turn emacs into a batch processor. You
can invoke commands and load lisp files for purely automated testing without
the -batch flag, and that is exactly what we are doing. I was calling that
batch mode, but now I don't know what to call it.

I mean start a

Well, this is literally all the information I have: the stdout
http://fommil.com/github.com/ensime/ensime-emacs/drone/ee99fc5d368cafc2dd583520f9fe8e9e23faadb6
from running this script
https://github.com/fommil/ensime-emacs/blob/drone/test/run_emacs_tests.sh
The last thing we see is the output from this function call (which starts the
process)
https://github.com/fommil/ensime-emacs/blob/drone/ensime-startup.el#L215
So I'm interested to know what implication the -batch flag has for the
functionality of emacs. Specifically: launching/monitoring processes, and
navigating buffers (i.e. spoofing user actions).
